1SAFETY

1.1 Purpose

The Duo 200 is intended solely for medical applications. You can use the Duo 200 for electrotherapy. The device is suited for continuous use.

1.2 Safety instructions

1.2.1 General

• Only qualified people who are trained in the application of the

therapies may use the appliance.

• Only a technician authorised by GymnaUniphy N.V. may open

the equipment or the accessories.

• Follow the instructions and directions in these user

instructions.

• Place the equipment on a horizontal and stable base.

• Keep the ventilation openings at the bottom and rear of the

equipment free.

• Do not place any objects on the equipment.

• Do not place the equipment in the sun or above a heat source.

• Do not use the equipment in a damp area.

• Do not let any liquid flow into the equipment.

• Do not disinfect or sterilise the equipment. Clean the

equipment with a dry or moistened cloth. See §5.

• Only treat patients with electrical implants (pacemaker) after

obtaining medical advice.

• The 'Directive on Medical Devices' from the European

Commission (93/42/EEG) requires that safe devices are used. It is recommended to perform a yearly technical safety inspection. See §5.1.1.

• For optimum treatment, a patient investigation must first be

performed. On the basis of the findings of the investigation, a treatment plan with objectives will be formulated. Follow the treatment plan during the therapy. This will limit possible risks, related to the treatment, to a minimum.

• Always keep these user instructions with the equipment.

Duo 200

1.2.2 Electrical safety

• Only use the equipment in an area with facilities that meet the

applicable legal regulations.

• Connect the equipment to an outlet with a protective earth

terminal. The outlet must meet the locally applicable requirements for medical areas.

1.2.3 Prevention of explosion

• Do not use the equipment in an area where combustible

gases or vapours are present.

• Switch off the equipment when it is not used.

1.2.4 Electro Magnetic Compatibility

• Medical electrical equipment requires special precautions for

Electro Magnetic Compatibility (EMC). Follow the instructions for the installation of the equipment. See §2.

• Do not use mobile telephones or other radio, shortwave, or

microwave equipment in the vicinity of the equipment. This kind of equipment can cause disturbances.

• Only use the accompanying accessories that are supplied by

GymnaUniphy. See §7.5 and §7.6. Other accessories can lead to an increased emission or a reduced immunity.

Duo 200

1.2.5 Electrotherapy

• Do not use the equipment simultaneously with high frequency

surgical equipment. This combination can cause burning of the skin under the electrodes.

• Do not use adhesive electrodes with currents that have a

galvanic component, such as galvanic, diadynamic, MF rectangular, pulsed rectangular and triangular currents. With these currents, etching of the skin can occur.

• Check the electrode cables and the electrodes at least once a

month. Check whether the insulation is still intact. See §5.1.

• The safety standards for electrical stimulation advise not to

exceed the current density of 2.0 mA However, with iontophoresis treatments, we advise a maximum current density of 0.25 mÂ/cm the MF rectangular current. Exceeding this value can result in skin irritation and burns.

, because of using

• Always use sterilised gauze with iontophoresis treatments.

1.3 Medical Devices Directive

The device complies with the essential requirements of the Medical Device Directive of the European Committee (93/42/EEC) as most recently changed.

1.4 Liability

The manufacturer cannot be held liable for injury to the therapist, the patient or third parties, or for damage to or by the equipment used, if for example:

• an incorrect diagnosis is made;

• the equipment or the accessories are used incorrectly;

• the user instructions are wrongly interpreted or ignored;

• the equipment is badly maintained;

• maintenance or repairs are performed by people or organisations that

are not authorised to do so by GymnaUniphy.

Neither the manufacturer nor the local GymnaUniphy dealer can be held liable, in any way whatsoever, for the transfer of infections via the vaginal, anal and rectal probes and/or other accessories.
